Pure-FTPd and LDAP: How can I configure IP locks for users?

[EPrime]

I've just installed pure-ftpd and it seems to work nicely with the LDAP server..

However, I haven't been able to find any information on how to limit users so that they are only able to login from specific pre-configured IPs.. does anyone know how to do this?

Ofcourse, I'd like to store this information in the LDAP server as well. If you know of another FTP server that has LDAP and SSL/TLS support that can do this, I might consider switching if no solution exists for pure-ftpd.
